  • Patent number: 12072467
    Abstract: The present invention provides a wide-angle lens capable of obtaining a suitable negative power even when a thickness of a first lens is increased in order to increase strength against impact. The wide-angle lens 100 has a front group 110, an aperture 80, and a rear group 120. Assuming that a central thickness in an optical axis direction of a first lens 10 is T1 (mm) and a focal length of the entire lens system is f0 (mm), the following conditional expression: 1.500?T1/f0?2.000??Conditional expression (1) is satisfied. Therefore, it is possible to suppress the first lens 10 from being damaged by impact. In addition, it is possible to prevent the first lens 10 from becoming too thick to obtain suitable negative power.
